Be it known that l, VvTILLIAM R. JEAvoNs,

a citizen ofthe United States, residing at l provided with a housing for the reception of the spur-wheel by means of which the wick is l raised and lowered.

` raiser.

ln order to permit the wick to be raised and lowered with an minimum strain on the wick-raiser, the width of the space between the tubes is made somewhat greater than the thickness of the wick; but the upper ends of the tubes converge slightly toward the wick to prevent the formation of a space between the wick when in raised position and the ends of the tubes, as suchspace would interfere with the satisfactory operation of the burner.

lt frequently happens in the operation of these burners that some friction is developed between the wick and one or the other of the tubes, as by .the swelling of the wick or by the rusting or roughening of the perforated metal band or wick-carrier, which is placed on-the outside of the wickand by means of which the same is raised and lowered by engagernent with the spur-wheel of the wick This binding of the wick in the tubes, acting in some cases through a distance equal to the diameter of the wick-tubes on the spur-wheel, causes the wick to be tilted. As the tubes are generally inade of light metal, the upper portions of the tubes at points remote from the wicl-1-raiser will yield, causing a tighter engagement of the wick by these portions of the tubes, with the result that it is often impossible to elevate the portion of the wick remote from the wick-raiser above the tubes.

The object of my invention is to correct the defects noted and to insure an even elevation of the wick by the raiser. l accomn plish this object by means of the construction shown in the drawings hereto annexed,

whereinp Figure 1 represents alongitudinal sectional view through the central portion of a pair of wicketubes constructed in accordance with my invention. Fig. 2 re resents a transverse section taken on the ine 2 2 of Fig. 1,

the hollow boss'or chamber forythegspurwheel, as wellv as said wheel being omitted. Figs. 3 and 4; represent similar sectional details of modications of the invention shown 6 5 in the preceding figures. Fig. 5 re resents a detail of the outer tube shown in fiigs. 1, 2, aud 4.

1 represents an outer wick-tube, and 2 an inner wick-tube, said tubes'being connected lattheir lower portions, as by soldering. Between the tubes there is formed an annular space 3 for the reception of the wick 4.

5 denotes the supply connection for conducting oil to the lower end of this annular space, and 6 denotes the wick-raiser, the same being illustrated as a spur-wheel mounted on a shaft 7. This shaft may be inclined, as indicatedin Figs. 1 and 5, whereby a rotary movement w' l be imparted to the wick as it is raised and lowered.

The wick 4 may be provided with a wickcarrier 8, consistingol a sheet of perforated metal applied to the outside of the wick and extending from the bottoni'to a point somewhat below the top. The lower end of 8 is bent inwardly, and an upwardly-extending band 9 is soldered or otherwise suitably -secured thereto to form therewith a U-shaped support for the lower end of the wick. The annular space 3 is of greater width than is normally provided to erinit the free Inovenient of the wick-body etween the inner and outer wick-tubes. To cause said tubes to closely engage the upper end of the wick, the inner tube is flared outwardly and the outer tube inwardly to form a space therebetween, the width whereof is suitable to the thickness of the wick, as clearly illustrated in Fig. l.

1Notwithstanding the provision of the somewhat enlarged space between tubes 1 and 2, it frequently happens, as hereinbefore explained, that the wick will bind against one or both of said tubes at a point remote from the wick-raiser. I have found that by preventing the tilting of the wick in the section about the wick-raiser and at the lace where the power is applied to the wick am 'sasso space to substantially the width of the wick and carrier at the section of' said annular space which includes said wheel, such narrowed portion extending substantially from the to to the bottom of the wick-space. 6. he combination of a pair oi wick-tubes having an annular s ace therebetween, a

said carrier, substantiall as specified; A

7. The combination o a pan' of wicktubes having therebetween an annular space which is contracted at the upper ends of said tubes, a wick and wick-earner in said space, and a spur-wheel, Ineansbeing provided for narrowing the width of the space between said tubes' in the section which includes the spur-wheel to a width substantially equal to the width of the wick and carrier, the narrowed vsection thus provided extending both above and below said spur-wheel.

' 8. The combination of a pairL of wick-tubes arranged to form vtherebetween an annular s ace which is narrowed at the upper ends of tiie tubes to substantially the thickness ofthe wick, a wick in said space, a wick-raiser for said wick, and means providing a contracted section in said annular space, said section extendingfrorn near the bottom of the tubes to near the top thereof and including between its circumferential limits the wickraiser, substantiallyl as s ecified. f

9. The com ination of a 'pair of wick-tubes having therebetween an annular space for the reception of a wick, a wick and wick-carrier within said space, a spur-wheel carried by the y lwick, one of Sal bein of substantial outer tube and arran ed to vengage the wicl carrier and raise and ower'the same and the` wick and means vprovidlnrg; a narrowed' ver# l t ticallyfeirtendin ysection o he annular space between said .tu es 'suchnarrowed sectiony ly the samewidth as the widt ofthe wick and carrier and'v extending -on both sides of the spur-wheel and sul sta1ntially from the bottom to the top ofthe wicktubes, substantially as specified. p

1o. The Combination of a pair -of wick! tubes having an annular space therebetween;

'a wick and wick-carrier in sai'd space, the upper ends of said tubes converging'to narrow the space therebetween at this point, a wickl raiser carried by thev outer 'tube and engaging the wick and carrier, one of said tubes having one or more projections extending'v into the annular space and so arranged as to narrow the-width thereof at lone section only, such?s narrowed section extendingverticall rolnx" the lower to the up er portion of s ai tubesf Y. and circumferentia y on sides of' the? wick-raiser.

11. The combination of a pair of tubes having therebetween an annular space which is contracted at the .upper end of said. tubes, a wich and wick-carrier in said space anda spur-whepl engaging said carrier and tubes having one or'more projections extending into the annular space to form a contracted ornarrowed section thereof, said narrowed section extending 'from the upper to the lower portion of sai space andlcxtendinglaterally on both sides of the spur-wheel.

In testlmony whereof l hereunto .affix i the resence f two witnesses.
